While we lament the shortfalls in the M720's mobile OS support, we have to admit that it's nifty to have one mouse that can be shared among three systems. This is especially useful in the cross-platform world, where many of us have some combination of at least a Mac and PC, or more than one computer of the same platform designated for work and personal use. In between the two mouse buttons sits a battery-status LED (which we never saw lit, since the battery was in good shape), a button, and forward of that, the scroll wheel. The scroll wheel is pronounced, with a prominent raise and a ribbed texture. The wheel is touted as "hyper-fast," and that claim doesn't feel very far off from our experience with the mouse. We flew through scrolling tasks, with little stress on our joints or muscles. Stopping precisely proved more challenging; we'd classify it as almost-too-fast scrolling. That latter toggle-and-connect button is the one that switches the mouse's connection among the three possible connected devices.

The mouse contains buttons and gesture support that make it ideal for use with tablets as well as PCs. The Logitech Options software enables users to configure / alter the behavior of the configurable keys of all the attached compatible Logitech devices. The Unifying Receiver program can also be triggered from within this interface. The battery status of the devices can also be viewed through this program. While it is difficult to find scope for improvement in the M720 Triathlon, the K780 can be made a little more attractive with full-height arrow keys (that would go well with the PC use-case). The keys in the K780 are easier to type on and provide a better usage experience compared to the ones in the K480.

The device-change mechanism for the keyboard has been altered. Instead of a rotary dial (used in the K480), the K780 uses multiplexed function keys for the same purpose In our review process, we first connected the M720 Triathlon to a PC with its USB receiver. After installing the Logitech Unifying Software, we were also able to pair the K780 without using its USB receiver.

The M720 measures 4.5 by 2.9 by 2 inches and weighs 5 ounces. And, as we noted above, the mouse's design is right-handed only. Setup, Usability, and Impressions

Consumers can use either Bluetooth or a 2.4GHz RF Unifying Receiver (included with both products) to communicate with the host device Despite the curve being more pronounced than on the Logitech M330 Silent Plus , we found it worked well for our fingers to splay over the buttons. In fact, we liked how long and smooth the button mechanism was: We could push with the whole length of our finger, which in turn took stress off our joints.
